I don't sing because I'm happy. I'm happy because I sing. - William James

The most violent revolutions in an individual's beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.

We have ...as M. Ribot says, not memory so much as memories. The visual... tactile... muscular... auditory memory may all vary independently... and different individuals may have them developed in different degrees. As a rule, a man’s memory is good in the departments in which his interest is strong; but those departments are apt to be those in which his discriminative sensibility is high. ...[D]ifferences in men’s imagining power... the machinery of memory must be largely determined thereby.

It would seem that common sense and reason ought to find a way to reach agreement in every conflict of honest interests. I myself think it our bounden duty to believe in such international rationality as possible. But, as things stand, I see how desperately hard it is to bring the peace-party and the war-party together, and I believe that the difficulty is due to certain deficiencies in the program of pacifism which set the military imagination strongly, and to a certain extent justifiably, against it. In the whole discussion both sides are on imaginative and sentimental ground. It is but one utopia against another, and everything one says must be abstract and hypothetical.
